Jet Filter: 

  • All earth-retaining structures require a way to drain hydrostatic pressure off the back of a wall and provide soil filtration that will stop soil fines from leaching out through the drainage system.
  • Drainage systems should provide two functions. They give water the easiest path to flow from behind a wall, and they provide soil filtration, so soil particles are not carried along with the water as it flows out from behind the wall.
  • Traditional drainage systems are buried behind the wall and under the backfill material. Over time, the performance of traditional drainage systems will decrease, and eventually, they become clogged and fail. When clogged, the water stacks up behind the wall and puts pressure against the wall. The water will force itself out by creating new drainage paths. This will cause damage to the wall and create voids in the soil as particles are flushed out.
  • JET Filter System provides maintainable weep hole filters, an innovative new drainage and soil filtration system for relieving hydrostatic pressure from behind earth-retaining structures. Maintainable weep hole filters replace or complement traditional drainage systems.

Pile Buck: How are maintainable weep hole filters better than traditional drainage systems?

Jet Filter: Eventually, all drainage systems fail. Since traditional drainage systems are buried behind the wall, they are not accessible or maintainable. Excavation and reconstruction are required. This is costly and disruptive. Maintainable weep hole filters install from the front of any new or existing wall. They are not buried under the soil. This means they are accessible. Being accessible makes them available for inspection and cleaning at any time.

To effectively address the Culvert’s drainage challenges at hand, the proposed solution included the drilling of 16 new weep holes, each 26 inches deep, and the insertion of 16 units of the JET Filter 4” diameter open-end drainage system

What is a Weep Hole? Enhancing Drainage and Soil Stability with the Jet Filter Weep Hole System

Weep holes are critical elements in various construction materials including concrete, steel sheet piles, and vinyl walls. They serve a fundamental purpose in managing water within structures, particularly in preventing accumulation that can lead to structural damage or increased hydrostatic pressure. While traditionally associated with moisture control, weep holes also play a vital role in soil retention and stability.
